I have one Computer on my test environment, I have been imaging multiple
times over the weekend

however today, the Boot Agent just exits on PXE after talking to the
Preboot Policy Server

I have run ZISEDIT
I had DD the master boot record

The policy should be looking at the mac address (which hasn't changed
since working on the weekend) However it just implies that there is no
work to do (although it doesn't state no work to do)

I can manually image the PC using PXE and Maint Mode.

Any idea's what is causing the policy to fail.
